Cycnium tubulosum, also known as the vlei ink-flower and the tissue paper flower, is a slender hemiparasitic perennial plant of the broomrape family. Its range includes much of southern and eastern Africa, from South Africa to Ethiopia, including Madagascar. It has creeping, straggling or upright stems, with few narrow, entire leaves and erect, white or pinkish, slightly zygomorph flowers on a long tube, with five lobes, reminiscent of a Phlox-flower. It may not always be fully dependent on the supply of minerals by other plants, but usually makes connections with the roots of grasses. It can be found in moist, short grasslands, reaching altitudes of about 1,550 m (5,090 ft). Its conservation status in South-Africa is "least concern".
